, comm, or an r i Be it known that I, r citizen of the United States, 'resi ful Im rovements in Automobile or Motor Cycle orns; and I do'hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainssto make and use the same;

This invention motor c cle hornsand more particularly to electric orns inwhich the sound producing device is controlled by an electric current,

theparticular object of my invention being to improve this type of horn in several particulars. v

One of the objects of my invention is to produce a compact condensed horn, in which the apparatus is so arranged that the horn may besuitable for mountmlgnupon the handle bars of a motor cycle. the use upon motor cycles the apparatus must be light and occupy ut little space, since there is very little room for this type of apparatus -u on the frame of the motor cycle, which is y crowded with the motor, gasolene tank and other apparatus employed in the operation of the machine. I p

Another object of my invention is to provide means for preventing the of current.

When the armature is adjusted, 'therelation between the armature and the switch is changed so that the time durinfiewhich the contact endures will'frequently 1n out of all proportion to what is necessary. Durin th1s surplus time current will be was and the batteries 'prema y exhausted. When manufactured the parts can be so arranged that the proper contact will he made with the least enditure of enarmature owing to wearing of otheryreajsons, the relation is I between the armature and the switc with which it o crates, when this and expen iture of energ W111 assrenon To me e ome aconrorron oroo.

at Elyria, in the county of Lorain and tate of Ohio, have invented certain new and userelates to automobile or Ins period Patented I w th, 1th.

Another object of my invention is to prowillfbe moved-or adjusted by the emplog- 'ment of a single devlce, and preferably, y adjusting these parts simultaneously;

Other objects of my invention and the invention itself will probably be better understood from a description of the particular embodiments.

Figural is a section of an embodiment of my invention showing one of the magnets in elevation. v

Fig. 2 is a diagram illustrating certain of g hie plarts employed in the form, shown in Fig. 3 is a plan view of the embodiment shown in Fig. 1 with the back cover removed.

Figs. 4, 5 and 6 are similar views of a second embodiment of my invention.

Referring now to the drawing and to the embodiments illustrated therem, I have shown the frame of the horn or signaling device, here illustrated as a frame piece 7, which is preferably made of a plate having a large opening 8 cut therein, leaving little more than a rim for the frame'piece 7. One of the edges of the frame piece may be turned 11 as shown at 9, substantially at right ang es to the frame piece 7, f0 u u," a

base or support 10, for a purpose to be e-' scribed. A sonorous' member, such as a through said open' The dia hra is d clamped around its efi p ime ges' beween the piece 7 which it engages directly, and a casmg front 13, which is provided with an opening 14 into which a resonator 15 maybe fastened in any suitable manner. The means for actuating diaphragm, here shown as electromagnetic means .1 consists p ferably of two ma ets mounted sul'rstantiagl ltglparallel to e diaphragm andv su P way.- In the form shown, the cores 16 ofthe magnets are connected at one end by scre s 17 to the member 10. The cores 18 project at one end, as shown at 18, beyond the windings 19, in order that they may exert mo flfrom'the member 10 in any suitab e influence over the armature 20, which is here shown as spanning the distance between the projecting ends of the poles 18, and is preferably located between such projecting ends and the diaphragm.

The armature is connected to the frame, preferably by spring means 21. A circuit, not shown, is provided for the electromagnetic means and a switch 22 in this circuit is controlled by the electromagnetic means, preferably through the armature-20. This switch includes contacts 23 and 2a which are preferably mounted on springs 25 and 26 connected to the frame. as shown. The spring 25 extends beyond the contact 23, as shown at 27. This spring is operated b the armature, preferably through a stu 2%, which may engage the projecting end 2'7. The contact springs are connected in any suitable manner to the frame.

The parts of a horn of this type are all adjusted at the factory when the horn is tested, but as the parts wear or for other reasons it becomes necessary to readjust them, I provide adjusting means for the armature 20, which is here shown as-a screw 30v fitted into a screw socket 31 which may be mounted on the diaphragm, the screw or socket serving as an anvil upon which the armature strikes to cause the diaphragm to sound a signal. It will be readily seen that if the armature were adjusted without adjusting the switch, it would be possible, and it sometimes happens, that the armature is moved so far toward the magnet in ad justing it as to open the switch 22, normally interrupting the circuit and making the device inoperative; or, adjusted the other way, the contacts 23 and 24 would remain in engagement longer than necessary, thereby wasting the battery current.

To obviate these faults, I provide means for adjusting the switch or moving the same at the same time that the armature is adjusted. In the form shown I have connected the switch to the adjusting means in such a way that when the screw 30 is moved both the armature and switch are adjusted. This may be done by a spring member 32 connecting the screw 30 to the frame and a stud 33 connecting the member 32 to one of the contact springs.

In the modification illustrated in Figs. 4, 5 and 6 the armature operates the diaphragm by striking a collar 101 upon the adjusting screw 102 mounted in a screw socket 103 which is upon the. diaphragm 104. The switch is shown at 105, consist ing of contacts 106 and 10? carried upon. the springs 108 and 109. lhe switch is operated by the armature through a stud 110 which engages the projecting end ill of the spring 108. The projecting end 114. of the spring 109 may be adjusted through the screw 102. In the form shown, an insulatmesses ing member acts to transmit movements from the screw to the spring, whereby the same is adjusted when the contact screw is operated.

The armature spring is normally stressed, so that the armature tends to move rearwardly, but is restrained by the spring 108.. When the screw 102 is forced inwardly, the armature will be released and move nearer the cores; at the same time, the switch will be moved upwardly through the member 110. When the screw is drawn outward, the springs 108 and 109, which are stronger than the spring 120 will force the armature toward the diaphragm, the switch following.

l have illustrated these two emboeuts of my invention for the purpose of clearlyezcplaining the same. I do not wish to be limited to the details of the apparatus illustrated in these embodiments, but contemplate numerous and extensive departures therefrom without departing from the spirit of m invention.
